1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Against the backdrop of a rapidly evolving multi-crisis era, the COVID-19 pandemic raises critical questions about how acute shocks may reconfigure perceptions of persistent environmental risks. Drawing on two representative surveys in Nanjing before (2018-2019, n = 508) and during (2022, n = 500) the pandemic, triangulated with geotagged Nanjing Weibo posts (2019-2022) and the World Risk Poll (2019; 2021), this study develops three theoretical models and tests eight hypotheses. Results reveal clear cross-crisis effects: COVID-19 significantly reduced perceived air-pollution risks, consistent with a finite-pool-of-worry account. This decline partially offset stress, yet the pandemic still produced a net increase in mental stress by introducing additional psychological burdens. Although COVID-19 reduced average daily PM
